`Na11kai (‘420) discloses a test strip (or “measuring device”) that includes

`
`I disagree that “there is no criticalitjr in
`
`arranging t:I1e reference electrode upstream," as argued by Pharmatnech Since t:I1e
`
`reference electrode in Nan]-:ai is placed downstream of the working electrodes,
`
`when insufficient blood is applied, the electrode that would be i.t£I£{2I:EIIIp.l.E‘lE.ljV
`
`covered would be the reference electrode rather than a working electrode.
`
`Coverage of a minor portion of the refenence electrode could cause a higher than

`oormalcurrentdensitjrtoflowinthecoveredpartofflaeelectrode, alteringthe
`
`ability of the reference electrode to prcrvide a stable potential agaimt which the
`
`Working electrode could be established and pfl‘l'£IlI2ifi.l.l'jF causing inaccurate
`
`measurements of glucose- Nanlcai would not detect an inaccurate measurement:
`
`made at any one of, or all of, the working electrodes; it would merely average the
`
`Ex. 2008 Declaration of John L. Smith
`
`inaccurate n1easuren:1ent(s)_ Nankai does not recognize t:he criticality of placing the

`reference electrode upstrearn from the working electrode fin ohtaining accurate

`measurements.

`Schulman
`“glucose sensor”
`
`Ex. 1007
`
`17
`
`

`
`Schulman
`“glucose sensor”
`
`Dr. Smith: “[T]he only use disclosed in Schulman for the W2
`electrode is to measure background oxygen. The W2 electrode
`does not generate charge carriers proportional to the
`concentration of glucose in a sample.” Ex. 2008, ¶63.
`
`18
`
`

`
`Dr. Smith: “Because Schulman uses two completely separate
`electrode systems for any duplicate measurement, each of the
`measurements is made with a separate reference electrode,
`rather than the ‘common reference’ of the ‘105 Patent.” Ex.
`2008, ¶74.
`
`Pharmatech: “LifeScan is correct; the working electrodes in the
`‘105 Patent share the same reference electrode while each
`glucose sensor assembly in Schulman includes its own reference
`electrode.” Paper No. 17 at 7.
`
`19
`
`

`
`Reasons Why No Motivation to
`Combine
`
`20
`
`

`
`Schulman v. ‘105 Patent
`Dr. Smith: ‘[W]hile both the ‘105 Patent and Schulman
`are broadly concerned with the measurement of
`glucose and both use glucose oxidase, the statement
`that they are both based on “GOx mediated electrical
`current is incorrect. … Every current disclosed by
`Schulman as being measured is due to the reduction
`of oxygen, not the reaction between GOx and gluose
`with subsequent oxidation of a mediator as disclosed
`in the ‘105 Patent. Schulman states this explicitly,
`stating ‘oxygen is consumed at the working
`electrode.’” Ex. 2008 ¶68.
`
`21
`
`

`
`Schulman v. ‘105 Patent
`
`Pharmatech: “While both Schulman and the
`‘105 Patent measure electric current to
`determine glucose levels, LifeScan is correct that
`the methodologies differ.” Paper No. 17 at 6.

`

`
`Advanced Display Systems, Inc. v. Kent
`State University, 212 F.3d 1272, 1285 (Fed.
`Cir. 2000)
`
`“Zhou's deposition also provides compelling evidence
`of nonobviousness by illustrating ADS's wholesale
`copying of the claimed invention. See Specialty
`Composites v. Cabot Corp., 845 F.2d 981, 991, 6
`U.S.P.Q.2D (BNA) 1601, 1608 (Fed. Cir. 1988)
`(reasoning that an accused infringer's close copying of
`the ‘claimed invention, rather than one in the public
`domain, is indicative of nonobviousness’).”
`
`25
`
`

`
`“I have examined the Pharmatech
`GenStrip test strips, and it is
`apparent that they are copies of the
`test strips illustrated and described
`in the ‘105 Patent (as well as of
`LifeScan’s commercial blood glucose
`test strips which embody the ‘105
`Patent invention.” … I have
`confirmed that these meters
`[LifeScan Ultra meters] when used
`with the LifeScan or Pharmatech
`test strips, carry out [the measuring,
`comparing, giving an error
`indication] steps recited in the ‘105
`Patent claims.”
